To @ZZ whom it may conccrn.-

Be it known that I, EVEEETT W. WALKER, a citizen of the United States ofAmerica, and a resident of Springfield, in the county of Hampden andState of Massachusetts, have invented certain new and usefulImprovements in Seats for Bicycles and other Vehi-y My improved saddleis illustrated in the accompanying drawings, in which Figure 1 is aplanView of the seat or saddle with a portion of the seat-top removed forclearer illustration of the parts therebelow. Fig. 2 is a rear elevationwith some parts in vertical cross-section. Fig. 3 is a sectional View indetail taken on theline 3 3, Fig. 2;and

Fig. 4E is a sectional view in detail taken on the line 4 4, Fig. 2.

Similar characters of reference indicate corresponding parts in all ofthe views.

In the drawings, A represents the saddle or seat frame, comprising theopposite pair of bowed or upwardly-curving members 1010, the same beingdivergent at the opposite ends of the frame, as shown in Fig. 1, theupwardlyextending portion at the ends of the members 10 lO beinginwardly continued a short distance in the section designated by 12 12,Which are united by the transverse members 13, and the seat-frame iscomposed of duplicated halves, each of Which is constituted by a singlelength of heavy and comparatively stiff Wire, the under-turned andapproached extremities of which are formed into eyes 9 9.

d represents the seatpost arm, which ranges forward and rearwardly onthe bicycle or other vehicle, but transversely relatively to the lengthof the seat, and B represents a split clamping-sleeve inclosed in themetallic box-like appliance J, said clampingsleeve embracing theseat-post arm a and confined thereto and the seat-post arm and sleeveconnected to the part J bythe clip 15, on the threaded extremities ofwhich are the confining-nuts 16.

The opposite vertical walls of the box-like fitting J support the bolts30 30, which are arranged in parallelism with eachother and with theyarm a, these bolts having' each a head at one end and a nut 32 at theother, and they form the members for the pivotal connection therewith ofthe eye-formed ends 9 9 of the heavy wire duplicated members, whichconstitute together the saddle-frame.

Sleeves or tubular distance-blocks 3%, with washers 35 of increaseddiameter, are interposed between the eye-formed ends of each half of thesaddle-frame for keeping these parts in their proper places on thesupportingbolts therefor.

36 36 represent blocks of anysuitable material-eas, for instance, rubberor woodinterposed between the portions 10 of the wire seat-frame whichare adjacent the eyes .9 and the top of the case-like iitting J,servswinging of the aforementioned Wire-formed part.

C represents the seat-top, the same being preferably constructed of acomparatively Wide blank of sheet metal, supported by the cross membersl13 of the frame and having and partially under the curved extremities ofthe frame and provided With the ears 18, which engage the adjacentportions of the placement of the said seat-top.

The opposite edges of the seat-top are downwardly turned on curvingcontours, as indicated at 19. This renders the top substantially rigidbetween its points of support on the seat-frame.

Rollers b b are placed to rotate upon the transverse members 13 13 ofthe seat-frame and directly support the seat-top.

D D represent a pair of horizontally-arranged spiral springs, having theend eyes 22,

ing to prevent an undue upward drawing or.

its opposite end portions 17 17 turned aroundv said heavy Wire frame andprevent the dis- IOO engaged with which are the rings 23, and engagedboth with the rings 23 and the transverse upper seat members 13 are thelinks 24, such links, rings, and the intermediatelyconnected spiralsprings D being normally taut or substantially so. An intermediatespiral spring E2 is also provided, the same having end eyes 221,connecting-rings 23* and links 24* being also provided, whereby the saidspring is held in suspension under the central longitudinal line of theseat, the said latter appliances, as indicated in Fig. 2, not beingtaut, but normally sagging somewhat below the seat-top C.

The weight of the rider on the seat causes the duplicated parts made ofthe heavy wire which constitute the seat-frame and lwhich have pivotalsupport at 9 9 to swing downwardly and outwardly on such pivots as the`center of motion, and this spreading of the seat-frame is against theresistance not only of the spring D D, which becomes stretched,

butalso of the curved under-turned extreinities 17 17 of the metallicseat-top, for it will be understood that the curved portions 1l 11 ofthe seat-frame in bearing against the said under-turned portion of themetallic seat develop a gradually -increasing pressure between theseparts.

The rollers b b, provided on the portions 13 of the seat-frame, rendermore easy and free the operation described and also tend to ob viatescraping or squeaking noises.

The intermediate spring D2, which may adv 1l, 11, and provided with theengaging ears.

18, 18, said top being supported on the opposite Lipper portion of saidframe and spanning vthe space therebetween, substantially as described.

2. A seat for bicycles or other vehicles consisting of a bowed andupwardly-open seatframe, the opposite portions 11, 11, thereof beingupwardly and outwardly inclined, and a seat-top having the downturnedportions 17, 17, bearing on the portions 11, 11, and pro vided with theengaging ears 18, 18, said top being supported on the extremities ofsaid frame, and extending across or spanning the space between saidextremities, substantially as described.

3. In a seat for vehicles, the seat-frame composed of duplicated halves,each consisting of a single length of wire comprising the intermediatesection 13, the sections 12, l2, the under-turned portions 11, 11, andthe bowed extremities l0, 10, terminating in the eyes 9, a commonsupport with which the eyes have pivotal connection as described, one ormore spiral springs between `and connected to the oppositely-arran gedparts 13, 13, of both the seat-f rame counterparts and the seat-top,substantially as described.
